AI Technical Summary
Technical Problem
As implantable medical devices become smaller, the limited space for batteries and electrical components restricts flexibility in component arrangement and movement, necessitating feedthrough connections and restricting device design.
Method used
Incorporating a passageway through the battery allows for flexible component arrangement and movement, enabling electrical connections to be routed through the battery without feedthroughs, using a battery case with headers and a housing to define the device's exterior surface.
Benefits of technology
This design provides additional space for components, allows for more flexible arrangement and movement within the device, and maintains the device's compact size while ensuring electrical connectivity.

Abstract
Batteries having a passageway extending therethrough are described. A battery may extend along a longitudinal axis from a proximal end to a distal end. The battery may include a battery case, an anode disposed in the battery case, a cathode disposed in the battery case, and a passageway defined by the battery case. The battery case may define an exterior surface of the battery. The battery case may include an outer wall, an inner wall, a distal header coupled to the outer wall and the inner wall, and a proximal header coupled to the outer wall and the inner wall. The outer wall may define an outer perimeter of the battery case, the outer perimeter being orthogonal to the longitudinal axis. The passageway may extend through the battery from a proximal opening at the proximal end to a distal opening at the distal end.
